Hello! We have been struggling with this for almost a month now, we’ve read through every post we have seen about it, and still have made little or no progress at all.
We have a pretty simple ‘shop’, a single button that unlocks 10 more levels and disables ads. It works on the editor, however, once we build it and upload the aab into Google Play, we are not able to finish the purchase. It should enter the UnlockLevel method, but it will not do so. Levels won’t be unlocked, ads will remain there, and the boolean won’t turn true (Purchase of product XXX failed due to Unknown).
We are still able to interact with the button, but it will display a ‘Item already purchased’ text, and after 5mins, we will receive a Google Play mail saying that our purchase has been refunded.
I’ve seen a lot of people with the very same problem than us, and we have tried to follow the mail’s solution, but it involves modifiying the graddle and we are quite new to Unity, so we haven’t been able to do anything at all. As far as we know, it may be something related to the Google Billing.
Unity 2019.2.8f1, IAP 1.06/2.2.2/2.2.7, none of them worked.

Sorry, I wasnt very clear before. The issue remains the same, I checked the “Consume” checkbox the very first day. I will try to have the logs for tomorrow!
Sounds good. Also, show a screenshot that shows your IAP products as defined on your Google Play developer dashboard, showing the same ProductIDs as you have listed in your game https://docs.unity3d.com/Manual/UnityIAPGoogleConfiguration.html . Ensure you download from Google Play as a tester to properly test IAP. Also, you won’t want to be using Codeless IAP since you will need to add code to customize.
If you look towards the bottom of the logs, I believe you will see the issue. “Purchase not correctly processed”. Again, I would recommend Scripted IAP for reasons like this.
Please use the Sample IAP Project, I would not be able to debug your game. Is your IAP Button active on the very first loading screen? Otherwise, are you using an IAP Listener on start? Scripted IAP avoids these issues.
@nullwaresoft Are you testing by first downloading from Google Play? This is necessary. What Android device are you testing on? Can you try with a new product? We’ve heard of other reports of the Unknown error, but we are not able to reproduce.
Yes, we are using the store to download the app through internal testing. We tested with three different products. Now we’ve tried with an empty project, same script, and we got a different error (product name is com.nullwaresoft.test.test, just to make the search easier).
With this project, we are not getting the refund mail (hence, we are not able to buy the product again after 5mins, since its a non consumable), however it doesn’t seem to be working either.
What is the error? Do you get the purchase dialog? Are you receiving ProcessPurchase? It looks like the receipt validator threw an exception, can you confirm? Please show your updated code, your previous code would not be expected to call UnlockLevel (which is checking for NONCONSUMABLE1). If this was a new project you are testing, did you generate new Tangle files?
Hey! I was able to get it working on the test project just by generating tangle files again, something must had gone wrong the first time. However, after doing the same on the other project, we are still getting the Unknown error.
We’re using the very same script, new tangle files, but we can’t get past this Unknown error. Both scripts here (first is the test project, second is the main one)

You said our code would not be expected to call UnlockLevel, however, it did work on the other script by enabling the image I referenced. Where would that piece of code go, then? It seems to be working there (and I doubt the Unknown error comes from that piece of code).
We’ll be testing our main project on Unity 2020 later today, since that’s the only difference between our both projects right now.
Update: it worked flawlessly after updating to Unity 2020.1.4f1 ! The only doubt that remains is how to handle several products, as I expect it would be through the ‘PurchaseProcessingResult ProcessPurchase’ method, but I’m not sure.
Got it! Interesting that it was Unity version related. Make sure you are not using a Codeless IAP Button if you are using scripted IAP. Each product will trigger ProcessPurchase, you can inspect the arguments to see which product it is.
